Height: 6'2"-7'10" depending on the individual and flower size (regular Venusaur stage)
Weight: 100-127lbs for their plant and about 2.5 tons for the animal itself
Scientific Name: SeminalemorphoBulbasaur is the name given to the infant stage of the Venusaur Line. The Latin distinguisher for Venusaur is
Seminalemorpho or Morphing Seeded One. Like all Pokémon, after a certain age if the right conditions are met, the Pokémon will undergo a spontaneous metamorphosis. The transformation is a rapid replacement of cells in the entirety of its body causing rapid growth and changes to the physical body. Unlike most Pokémon, Venusaur eggs actually lack the nutrients necessary for a fetus to grow successfully as they contain no yolk sacks for the fetuses to ingest. Using their specialized tusks (what many people mistake as teeth), a female Venusaur will locate a patch of a specific bulb plant known as
Rafflesia Tulipa, closely related to both the modern day tulip and the Vileplume line. The eggs are laid and then reburied underground near the roots of the plant which eventually locate and breach the shell.
Rafflesia Tulipa reproduce by injecting their seeds into the ground but are nutrient intensive meaning that they deplete the surrounding soil of its nutrients giving the plant a relatively short life.
However, once the shell of the Venusaur egg is breached, the seedling enters carrying with it, the essential nutrients for the fetal development of the young creature and thus an endosymbiotic relationship is born. Throughout development, the main surface bulb will pump in what nutrients it has left into the egg which will eventually carry its seedling. This results in the main bulb dying. The sex of the animal is determined by temperature. If the temperature is 30ºC/86ºF they will all be female; 34ºC/93.2ºF they will be male. Given that the eggs are buried during summer near the surface of the ground, most come to be male. Once fully developed, the Bulbasaur hatches using a rudimentary egg tooth and burrows to the surface. The Bulbasaur is now a lush green hue as the hybrid Animal-Plant creature (need scientific name) is now capable of kleptoplasty, the name given to an animal that can produce its own food via photosynthesis. With the development of the animal complete, both organisms converge to essentially create one organism. In exchange for a longer range for it to lay seeds and for a lifetime of nutrients, the bulb gives the Bulbasaur infant camouflage, protection (via toxic spores and exploding seeds) and a means of creating food without necessarily eating. At this stage, the bulb is now fused into the spine of the creature and thusly, the nervous system. Just below the head on either side of its chest, the Bulbasaur has two specialized muscular organs which can fire "vines" derived from its bulb with great dexterity and speed.
When threatened, Bulbasaur find a grassy patch and instinctively burry themselves leaving only the plant exposed which then releases a nauseating odor to ward off predators. On most days, the bulb releases a sweet/sour smell to attract insects who fall into the small undeveloped pitcher plant. As the Bulbasaur grows, it enters its first state of spontaneous metamorphosis becoming the juvenile Ivysaur. Now stronger, Ivysaur are now more prone to fighting and thusly are dangerous to trainers for their aggressive behavior. Their rudimentary tusks have grown more useful and are used for digging into the earth for nutrient rich roots. Ivysaur's claws have also grown, crucial for digging. Its previously small and stout legs have grown longer and sturdier through it can frequently be thrown off balance due to the bulb's increased size. The bulb itself is now in its budding stage and has metamorphosed with the Ivysaur. Alone, the bulb will never surpass its bulb stage and reach the grand flower status that sits upon the backs of Venusaur. Its petals are a vibrant pink. As the Ivysaur grows, the chemical composition of the plant changes as well giving it a sweet aroma. Like a ripened fruit, it is a determining factor that metamorphosis is near. Once matured, the second stage of metamorphosis is initiated creating the fully fledged Venusaur.
The organism has changed greatly during its second-to-third stage transformation. The tusks are now thicker and more stout. Its wrinkled, warty flesh is a survival mechanic to hold in water and keep the Venusaur from burning too easily in the sun giving it its Thick Fat ability. Its stout legs have almost moved sideways to support both its body and the massive reimagined plant on its back. The
Rafflesia Tulipa has become a beautiful pink/red pitcher plant with leafy growths emanating from under it. Though the Venusaur controls the plant mostly, it can still defend itself if prodded and will occasionally shoot a seed that plants itself into the ground. The sides of the inner pitcher plant are coated with a waxy substance preventing any insect Pokémon from escaping once inside and turning it into a gruesome insect soup (highly nutritious). Like most Pokémon, the Venusaur line is capable of breeding at any stage, increasing its chance for survival given the fact that females are statistically rare.
Venusaur travel in herds led by an Alpha Female and her group of male mates. New groups usually form around the mating season in Winter when groups of males will follow the sweet aroma of the Female's plant. After the season is over, the groups will remain together with the males that the female has chosen. This is the only time that males will spar unless kicked out of their previous groups. When mating, males compete with Headbutts, Vinewhips and bellowing.
In almost all cases, the females are larger and more physically strong. Herds usually range from 6-12 individuals and their young but some researchers have observed groups as large as 30. In herds, evolution is commonly a ritual pack event. Like migrating elk, during a particular season in a particular place (the season and location differ between every unique region, except for Kanto and Johto, which share a location) where they evolve into Ivysaur and then they generally scatter into their old herds again, though sometimes Venusaur offspring may get lost and join other packs instead (which are generally incredibly welcoming of the new members).
Mega Evolution in the Venusaur species, like all Pokemon species capable of Mega Evolution, is still an incredibly mysterious and peculiar process. Radiation from the Mega Stone, Venusaurite, is amplified by a keystone (generally attached to a simple ring, bracelet, or necklace accessory) and effects a change in forms similar to regular Evolution Stone Evolution except that this metamorphosis is not permanent because the radiation wears off and requires time to ready itself for another use. The Mega Stone acts like a natural battery and requires constant charging though the science behind this metamorphosis "charging" is still hazy and unclear though many speculate it has something to do with the positive relationships between trainers and their Pokemon.
They live up to 80 years in captivity and about 55 years in the wild. The
Rafflesia Tulipa that is growing on Venusaur's back doesn't immediately die when the body dies. The vines from the plant sense that they have lost their symbiotic energy source and seek the earth to keep living. Often, the Venusaur begins feeling ill and secludes himself to go die alone (though captive species have been known to die with their trainer by their side because they possess a different bond with them than that with fellow members of their herd). Afterward, the herd will seek out the dead body and bury it with their large digging tusks with as much dug up earth as possible, burying only the body portion and not the plant top. Trainers generally require much more assistance in burying the behemoth Pokemon. The
Rafflesia Tulipa plant from their backs continue to sprout and now reach a point in their life cycles when they will begin to seed further and grow fields of
Rafflesia Tulipa, which later will become the egg burying grounds for a future generation of the herd's Bulbasaur eggs, which will provide new seedling plants to help the unborn babies live in the future but consequently kill of the main bulb, as always. This is the Venusaur's own unique circle of life process, where the Pokemon individual still continues to "live on" after death to help another generation by sacrificing its own "life".
